CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 252,742, dated January24, 1882.

Application filed September I, 188i.

(No model.)

:sylvania, have invented a certain new and useful ImprovenientinCurtain-Fixtures, of which the following is a specification.

This invention has more particular reference to thatclassofcurtain-fixtures inwhich the entire fixture, including the roller, canbe adjusted to difierent heights with relation to the window, butit isin part applicable to curtainfixtures in which the bearin gs for theroller are in fixed brackets. r

The invention consists, first, in the devices for rolling and unrollingthe curtain and securing the same so that it can be raised or lowcredand retained in any position by means of a single cord; second, inthecombination, with said devices, of means for raising and lowering theentire fixture independent of. the rolling and unrolling of the curtain;third,in the details of construction and combination of parts, ashereinafter more fully set forth.

The accompanying drawings, which form a part of this specification,represent a curtainfixture constructed in accordance with the invention.

Similar letters of reference indicate like parts on all the figures. 1

Figure 1 is a perspective view of the ho proved curtain fixture in placeupon a window; Fig. 2, a similar view of the end of the roller uponwhich are the devices for rolling and securing the curtain; Fig. 3, asectional view of that part of the device shown in Fig. 2; Figs.4, 5,and 6, detail views; and Fig.7, a

sectional view of the knob for securing the main curtain-cord.

A is the window-frame, provided with rollers or buttons a aat the uppercorners,fron1 which the curtain and its fixtures are smpended by themain cord B. One end of this cord is attached to the movableguidepieceb, which also forms one of the bearings for the roller 0, andthe other end is attached to a swinging piece or disk, D. The cord B ispassed from guide-pieceB over button a, then through the wire link orloopl), then upward and over buttons a a to the swinging disk D.

The whole curtain may be raised orlowered by means of the single cordE,caught by a knot in link I), and is secured by means of thedouble knobF. I

The rolling or unrolling of thecurtain is accomplished by means ofacord, c, which winds on a spool, c, at one end of roller 0. This cord 0passes through a slot in arm clof swinging disk D. When the curtain isdown the cord is wound aroundthe spool, and in raising it the cord isdrawn'down as customary.

On the end of roller 0 is secured a cap or disk, 0 which is preventedfrom twisting by means of lugs 0 which take into the end of the roller.To this cap or disk is attached a second disk, G, provided with acollar, which forms the spool for cord 0. Projections g on said collarfit into corresponding holes in disk or cap 0 On the opposite side ofdisk G is a hub or boss, g, and acollar, 9 forming a continuation ofsaid-hub or boss. Both disks 0 and G have a central hole for the passageof a screw, 9 which screws into roller 0, and the head of which, whensecured in place, bears against collar 9 and clamps disksGand c androller 0 firmly together,

The swinging piece or disk D (see Fig. 5).

hanger (see Fig. 6) has a hole, 0, in its lower end to receive collarand constitutes the bearing for roller 0.

On the side of disk G adjacent to the swinging disk D are a'number oflugs or projections, 9 arranged at equaldistances from the center toform a ratchet-wheel. Swinging disk'D has a single projec tion, dwhiclnwhen collar 9 is in the back or lower part of slot d, engages withone of projections on disk G and arrests the rotation of the roller.

The device for fastening cord E, by which the height of the fixture isregulated, consists of two knobs, ff, and a screw, f by which the knobsare secured to the window-frame. \Vhen the fixture is brought to thedesired place the cord E is wound between knobsff and is secured by thepressure of their adjacent'surt'aces. For purposes of adjustment todifferent thicknesses of cord' the head of screw f is made square, asshown, and fits into a square hole in knobf, so that byturning thelatwith one of the projections g.

arrests the roller.

ter the distance between theknobsis increased or lessened, thus allowingthe use of cord of greater or less thickness.

The operation of the device will be readily understood. The weight ofthe fixture keeps the collar normally in the lower or back part of slot(1, the projections d being in contact To raise the curtain or shade,cord 0 is pulled downward. The pressure upon arm d of swinging disk Dthrows the lower portion of the latter back, thus throwing projection dout of engagement with projections g and the roller 0 is permitted torevolve, thus rolling up the curtain. When raised to the desired heightcord 0 is suddenly released and projection 01 entersinto one of thespaces between projections g and To unroll the curtain or shade,swinging disk D is thrown back by pulling on cord 0, as before, and thecord held with sufficient tension to keep projections d and g out ofengagement, while the weight of the curtain causes it to descend. As thecurtain descends the cord 0 is permitted to slip between the fingers andis wound upon spool c.

The guide-piece 1) serves to keep the curtain in place against thecasing and close to the window.

Modifications maybe made in the details of construction withoutdeparting from the spirit of the invention.

Having now fully described our said invention and the manner of makingand using the same, what we claim is-- 1. A swinging disk, D, providedwith a projcction on its inner face, and having a slotted arm, throughwhich passes the curtain-cord, in combination with a second disk securedto the end of the curtain-roller, and provided with a spool, 0, a seriesof lugs or projections, 9 and a collar, g substantially as and for thepurpose described.

2. The combination of a swinging disk having a projection, d, a hangingpiece or hearing, 6, supported by said disk, a second disk secured tothe curtain-roller, and provided also with a collar which passes througha slot in said swinging disk, andacord passingthrough a slotted arm insaid swinging disk, substantially as described.

3. In a curtain-fixture, the combination of the main cord for supportingthe same,a swinging disk to which one end of said cord is attached, ahanging piece or hearing supported by said swinging disk, devices, asspecified, for rolling and unrolling the curtain and holding the same inposition, and a double knob for securing said main cord, substantiallyas described.

4. Thecombinationof swingingdisk D, main cord 13, attached thereto, diskGr, provided with fastening devices, as specified, guide-piece b, towhich the otherend of said cord is attached, link I), cord E, and knobF, substantially as described.
